    If the battery does not pop up, use a small plastic flat-blade tool to pry up the battery 
    2.  
    around the battery latch. If the battery is swollen, replace the battery. See below.
    Try a new battery.
    3. 
    Verify proper latch operation by exercising the latch. If it does not move smoothly or evenly, 
    4.  
    try disassembling the battery latch. Check that the spring held between the latch cover and 
    the battery latch pin is intact. 
    Replace the bottom case.
    5. 
    If the latch does exercise correctly, verify that the customer is not installing the battery with 
    6.  
    excessive force or the body of the battery has not been deformed around its perimeter.
    Warning: If the battery plastic housing has been damaged, or the two halves of the 
    housing have separated, the battery is unsafe for use.
    Note: If there is no sign of abuse (dents, scratch marks) replace the battery under warranty.
    Swollen battery
    Symptom(s):
    1.  
    The computer may not run off battery power alone
    • 
    The computer wobbles and won’t sit flat on a flat surface
    • 
    The trackpad button is continually pressed and doesn’t release (in this case, test by 
    • 
    removing the battery to see if the trackpad button functionality returns).
    A swollen battery can expand and cause the battery case to break open, exposing cells. 
    • 
    Use care and common sense when handling a battery with exposed cells.
    If the bulged battery will not release/come out of the unit, try removing the top case to help 
    2.  
    release the battery. 
    Replace the battery.

    The battery won’t charge
    Remove any externally connected peripherals.
    1.  
    Try a known-good power outlet.
    2.  
    Connect a known-good MagSafe 85W power adapter with power cord or plug. If the DC plug 
    3. 
    is properly inserted, the LED should light up. If not, troubleshoot the MagSafe connection 
    and power adapter. If the LED is green, turn over the computer and press the battery button. 
    The battery lights should glow green and stay on if the power adapter is operating correctly.
    Try a known-good battery. If it charges, replace the battery. If doesn’t charge, check the 
    4.  
    battery connector and its connection to the logic board.
    Reset the SMC (power manager) as described in “
    5.  Resetting the System Management 
    Controller (SMC)”  under “Troubleshooting Tips and Tricks” in the previous section.
    Make sure the left I/O cable is firmly connected. Look for damaged insulation or wires.
    6.  
    Replace the battery connector assembly (requires removing the logic board).
    7.  
    Replace left I/O power cable.
    8.  
    Replace the left I/O board.
    9. 
    Replace logic board.
    10.  
    Battery won’t charge completely
    If the battery appears to stop charging between 95 and 99 percent, this is normal operation. 
    Refer to Knowledge Base article 88344: Apple portable computer’s battery does not show a full 
    charge in Mac OS X. 
    Short battery life
    Three categories to consider:
    There is a system issue (not the battery).
    1.  
    If you have the customer’s power adapter, plug it into a known good outlet and verify 
    • 
    that it can charge the system. Also make sure it is the correct 85W adapter.
    Plug a known good 85W adapter into a known good outlet. Verify that the DC connector 
    • 
    is fully seated into the computer.
    Check whether the customer’s system is set up for heavy battery power use (AirPort on, 
    • 
    optical media always in drive, Energy Savings set to Highest Performance, etc).
    Use Activity Monitor to check for any runaway applications. Stop any runaway processes.
    • 
    Test the computer with all third-party devices (printers, hubs, third-party keyboard or 
    • 
    mouse) removed.
    Reset the SMC (power manager) as described in “
    •  Resetting the System Management 
    Controller (SMC)”  under “Troubleshooting Tips and Tricks” in the previous section.
    The battery needs calibration, or it is nearing the end of its useful life.
    2.  
    Calibration should be done when you first use the battery, and every few months after. It 
    •  
    						
    							MacBook Pro 17-inch (original, Core 2 Duo, 2.4/2.6GHz, 2008) Troubleshooting — Hardware Symptom Charts 17 6
    allows the battery to properly calculate how much power is left in the battery.
    The battery is a consumable part. It can be charged and discharged only so many cycles 
    • 
    before it becomes depleted and can no longer hold a charge.
    Note: The battery calibration procedure is as follows: Plug in the power adapter and fully charge your battery until the light on the power 
    a.  
    adapter plug changes to green and the on-screen meter in the menu bar indicates 
    that the battery is fully charged.
    Allow the battery to rest in the fully charged state for two hours or longer. You may 
    b. 
    use your computer during this time as long as the adapter is plugged in.
    Disconnect the power adapter with the computer on and start running it from the 
    c. 
    battery. You may use your computer during this time. When your battery gets low, 
    you will see the low battery warning dialog on the screen.
    Continue to keep your computer turned on until it goes to sleep.  
    d. 
    Note: Save all your work and close all applications when the battery gets low, before 
    the system goes to sleep.
    Turn off the computer or allow it to sleep for five hours or longer.
    e. 
    Connect the power adapter and leave it connected until the battery is fully 
    f. 
    recharged again.
    3.   The battery has a defect.
    Symptoms include, but are not limited to, a relatively new battery that will not charge 
    • 
    at all, reports an “X” in the menu bar icon, or a status light on its case that will not go 
    out. In the first two cases, the battery may need calibration—try this first. In addition, 
    after troubleshooting at the system level, if it is demonstrated that the battery is causing 
    abrupt shut-downs or goes to sleep without warning, the battery can be considered 
    severely degraded and follow the criteria at the beginning of this section.

    3. 
    Replace with known-good Bluetooth card.
    4.  
    Replace logic board.
    5. 
    Display
    Display latch not working
    Note: As the display is being closed, two latch hooks in the top of the display housing should be 
    magnetically pulled down through the slots in the top case and secured by the latch mechanism. 
    When the latch button is pushed, the hook should release and retract into the display housing.
    See Latch	Adjustment chapter for more information on adjusting the latch mechanism.
    If one or both of the latch hooks are broken, replace the display latch hook assembly.
    When displaying a single color over the screen area, the LCD panel shows one or 
    more pixels that are not properly lit
    To determine whether or not the display has an acceptable number of pixel anomalies, follow the 
    steps below:
    Set the display image to one of the following colors: all-white display, all-red display, all-green 
    1.  
    display, or all-blue display. Knowledge Base article 112125: Service Diagnostics Matrix, has the 
    LCD Tester Diagnostic Utility that will generate these patterns on the screen.
    Using a jeweler’s loupe, pocket microscope, or other magnifying device, identify and count 
    2.  
    each pixel anomaly:  
    • Bright subpixel anomaly = subpixel that is always on 
    • Dark subpixel anomaly = subpixel that is always off
    Acceptable Number of Subpixel Anomalies
    Bright Up to 3
    Dark Up to 5
    Combination Up to 7 
    						
    							MacBook Pro 17-inch (original, Core 2 Duo, 2.4/2.6GHz, 2008) Troubleshooting — Hardware Symptom Charts 17 8
    If the number of subpixel anomalies exceeds the acceptable number listed in the above 
    3. 
    chart, replace the display panel assembly.
    Replace
    Bright 4 or more
    Dark 6 or more
    Combination 8 or more
    If the number of subpixel anomalies is acceptable, explain to the customer that the pixel 
    4.  
    anomalies are within specifications, and no repair is necessary.
    Important: Do not release the specifications to customers. Instead, inform them that a certain 
    number of subpixel anomalies are considered acceptable, and these factors apply to all 
    manufacturers using LCD technology—not just Apple products. 
    When speaking with customers, please use the following explanation:
    Active-matrix LCD technology uses rows and columns of addressable locations (pixels) that 
    render text and images on screen. Each pixel location has three separate subpixels (red, green, 
    and blue) that allow the image to be rendered in full color. Each subpixel has a corresponding 
    transistor responsible for turning the subpixel on or off.
    There are typically millions of these subpixels on an LCD display. For example, the LCD panel used 
    in the Apple Cinema HD display is made up of 2.3 million pixels and 6.9 million red, green, and 
    blue subpixels. Occasionally, a transistor does not work perfectly, which may result in the affected 
    subpixel being turned on (bright) or turned off (dark). With the millions of subpixels on a display, 
    it is quite possible to have a low number of faulty transistors on an LCD. Therefore, a certain 
    number of subpixel anomalies are considered acceptable. Rejecting all but perfect LCD panels 
    would significantly increase the retail price for products using LCD displays. These factors apply 
    to all manufacturers using LCD technology—not just Apple products.
